This invention relates to. improvements in I electrical condensers,particularly condensers for use in connection with radio apparatus.

An object of this invention is to provide a condenser of the typeadapted to carry a high electrical resistance, generally termed agridleak resistance, the supports for the resistance being directlyconnected to the elements to be of opposite potential in the condenser,such supports being preferably constituted of integral extensions ofsaid elements.

The nature and objects of the invention are fully set forth in thefollowing description and accompanying drawings; but the disclosure isillustrative only and I may resort to all variations of structure thatare embraced within the meaning of the terms of the appended claims.

On the drawings, a

1 he same numerals identify the same parts posite extremities of thebody of the con- I denser, the portions which project being bent upwardor laterally with respect to the body the condenser, such portions beingindicated by the numerals 3 and 4, and belonging to the elements 1 and 2respectively. The bent ends of the portions 3 and 4 have holes 5 toreceive the pointed ends of an electrical resistance member 6. Theextensions 3 and 4 make terminals for the condenser and enable both thecondenser and the resistance to be connected to the opposite extremitiesof an electrical circuit.

2. An electri #al condenser comprising at least two overlapping elementsof difl erent potential separated by dielectric material, each of saidelements having an extension to engage an electrical resistance memberto be mounted on the condenser, and means for retaining said elements inoperative relation to each other.

3. An electrical condenser comprising at least two overlapping elementsof differentpotential separated by dielectric material, each elementhaving a terminal projecting out of the body of the condenser, saidterminals being at opposite ends thereof, each terminal being shaped toengage an electrical resistance member to be mounted on the condenser,and retaining means encircling said overlapping elements to secure themin operative relation to each other.

55. An electrical condenser comprising a plurality of armatures ofopposite polarity separated by dielectric material, the armatures beingadapted to support an electrical resistance element and to connect thesame in circuit with the condenser.

6. An electrical condenser having a plurality of armatures of oppositepolarity in the form of plates, said plates extending from the condenserbody and serving as the sole means of support for a grid leak resistanceused in combination with the condenser.

'7. A grid leak comprising a condenser having armatures of oppositepolarity with integral extensions from the body of the con denser, aresistance element mounted between and supported by said extensions, thelatter also serving as terminals for the condenser and resistanceelement.

8. A grid leak comprising a stack condenser having arinatures ofresilient material extending from opposite sides of the stack, aresistance element mounted between and supported by said resilientextensions, the latter also serving as terminals for the grid leak.
